This web special predated the main TV series and is a fun individual little story to bring the characters to animation for the first time. Chiyo brings a video camera to school and chaos ensues once Tomo gets hold of it. Tomo’s rampage is captured in a series of brief cuts. The use of the camera’s POV is interesting and well handled, and the very short runtime is used efficiently to cover most of the familiar characters, with everyone doing something characteristic. It’s stylistically somewhat different from the TV series, with a different cast so it has a different feel, and the punchline at the end is hilarious.
This is definitely worth watching for fans and is even enjoyable as a standalone, but why would you keep it as a standalone?
